If you like to alternate high-intensity trainings with lighter trainings, consider the BH Fitness i.Air Mag HIIT spin bike. This machine uses a unique combination of air resistance and magnetic resistance to provide a very diverse range of trainings. HIIT is short for high intensity interval trainings. The air resistance, which increases as your movements become more intensive, is very suitable for that purpose. You can also use the machine for a standard spin session by linking it to an interactive application on your phone or tablet. It has a convenient built-in mount to place your tablet on. The i.Air Mag HIIT is made of sturdy materials, making it suitable for use in the fitness studio.
